The given bar graph indicates production of salt (in lakh tons) by 3 different companies P, Q and R from year 2016 to 2020.
Production of salt by company A, B and C from 2016 to 2020.
Find the ratio of average of production of company A and the average of production of company B from 2016 to 2020?
Answer & explanation
Correct answer: option 2
Sum of production of company A from 2016 to 2020 = 80 + 70 + 80 + 100 + 120 = 450
Average → \(\frac{450}{5}\) = 90
Sum of production of company B from 2016 to 2020 = 60 + 75 + 90 + 100 + 115 = 440
Average → \(\frac{440}{5}\) = 88
Ratio → 90 : 88
45 : 44
